TOY CRANE.

Specification of Letters Patent. Patented J an. 24, 1922.

Application filed July 17, 1920. Serial No. 397,018.

To all whom it may concern:

Be it known that I, Gnoncs ZAHORSKY, a citizen of the United States ofAmerica, residin at Detroit, in the county of Wayne and tate of Michian, have invented certain new and usefu Improvements in Toy Cranes, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

The invention relates to to s and refers particularly to toy cranes. neobject of the invention is to provide a simple structure which simulatesa usual construction of working crane, Another object is the productionof a structure, the parts of which can be formed of stampings. Furtherobjects of the invention reside in the novel arrangements andcombinations of parts, as more fully hereinafter set forth.

In the drawings:

Figure 1 is a perspective view of a toy crane embod ing my lnvention;

Figure 2 1s a longitudinal section therethrough;

Figure 3 is a rear elevation thereof.

1 is the truck having the de nding side flanges 2. 3 are shafts extening through the side flanges and having at their opposite ends thewheels 4, the rims of which extend above the platform 5 of the truck. 6is a housing having substantially the appearance of a working crane cab,and comprising the side walls 7 connected by the integral top 8, and thebase 9. This base is transversely arched-to reinforce the same and hasthe upright side flanges 10, which are slotted for receiving the struckout tongues 11 at the lower ends of the side walls 7, whereby the sidewalls are secured to the base.

For the purpose of permitting of rotation of the housing 6 relative tothe truck 1, the standard 12 is rovided, having upright side flanges 13with tongues 14 at their upper edges, which extend through suitableslots in the base 9, and are clinched thereover for securing thestandard to the flooring. The base 15 of this standard is pivotallyconnected to the platform of the truck as at 16. The side flanges 13 areof sufficient height to raise the base above the wheels 4 so that uponrotation of the housing, it will not come into contact with the wheels.

17 is the hoist arm of channel cross section and preferably ofincreasing width from its outer to its inner end. This arm is to theslde walls 7, and has at its outer end the pulley or sheath 19 locatedbetween the side flanges 20 of the arm and pivoted thereto. For holdingthe arm in various positions of vertical adjustment, there is a flexibleconnection 21 between the arm and the top 8 of the housing. 22 is aguide near the outer end of the arm, comprising a U-shaped memberbeneath the pulley or sheath for guiding the flexible connection passingthereover.

23 is an electro-magnet to which is connected the flexible connection 24which extends over the pulley or sheath 20 and is connected to the hoistdrum 25, which is located within the housing 6 and is rotatabl mountedupon its side walls 7. 26 is a crank fixedly secured to this hoist drumand located outside of the housing for winding or pivotall connected atits inner end, as at' 18,

unwinding the flexible connection 24 upon the hoist drum. 27 is abattery, such as a dry cell, removably mounted within the housing 6 andadapted to be connected to the electro-magnet 23 by means of theelectrical connections 28 and 29 which pass over the 1 struck out tongue30 bent to form a hook:

upon one of the side flanges 21 of the hoist 17. The battery isremovably held in place by means of the clip 31, the walls of which Aconverge forwardly to tightly engage the battery upon the latter .beingforced into the 01111). This clip is suitably secured to the base 9 ofthe housing, as by means of the tongues 32 extending through suitableslots in the base and clinched thereover. The forward end contact 33 ofthe battery is adapted to engage the contact 34 mounted upon the baseand insulated therefrom by the insulation 35. The electrical connection29 is connected to this contact. The rear contact 36 of the battery isadapted to be electrically connected to 28 by means of the resilienttongue 37 ivoted upon the handle 38 which is integral with the base 9,the electrical connection 28 being connected to the forward end of thebase. Thus to magnetize the electro-magnet 23, it is necessary merely todepress the resilient tongue 37, when the circuit will be completed fromthe forward contact 33 of the battery through the contact 34, electricalconnection 29, the winding upon the electro-magnet 23, the electricalconnection 28, the'base 9 of the housing, the resilient tongue, 37, andthe rear contact 36. To break the circuit, it is simply necessary toremove the thumb or finger from the resilient tongue 37 when the latterwill spring away from the rear contact 36.

In order to reinforce the handle 38 and at the same time make the sameless dangerous, when gripped to manipulate the toy crane, and of betterappearance, it has the depending side flanges 39 terminating in theinwardly extending flanges 40. The handle 38 and base 9 are alsoreinforced by the longitudinally extending beads or corrugations 41,which further position the battery 27.

Due to pivoting, the resilient contact 37, upon the handle 38, thecontact may be rotated to permit of ready removal of the battery 27.

The'housing 6 with its base 9, clip 31, standard 12, truck 1, wheels 4,hoist arm 17, and pulley or sheath 19, may all be formed of pressedsheet metal, thereby decreasing the cost of manufacture. Furthermore,these parts and particularly the hoist arm 17, may be apertured todecrease their weight. I

What I claim as my invention is:

1. In a toy crane, the combination with a housing, of a hoist armmounted thereon, an electro-magnet adapted to be carried by said arm,and a battery within said housing and adapted to be electricallyconnected to said electro-magnet.

2. In a toy crane, the combination with a housing and a hoist drummounted thereon,-

of a hoist arm mounted upon said housing, an electro-magnet carried bysaid arm, a flexible connection secured to said electromagnet and hoistdrum and. passing over said hoist arm, a battery within said housing,and means for electrically connecting said battery to saidelectro-magnet.

.3. In a toy crane, the combination with a housing and a hoist drummounted therewithin, of a hoist arm pivotally mounted upon said housingand having a rotatable pulley at its outer end, an electro-magnet, aflexible connection between said electromagnet and hoist drum passingover said pulley, a battery mounted within said housing, and means foryieldably electrically connecting said battery with said electromagnet.

4. In a toy crane, a housing comprising integral side walls and top anda base, said said base and insulated therefrom, said contact adapted toengage a contact of the battery, and a resilient tongue electricallyconnected to said base and adapted to engage a second contact of thebattery.

7. In a toy crane, the combination with a truck and wheels upon saidtruck extending above the platform thereof, of a housing rotatablymounted upon said truck and a U- shaped standard having the base of itsU pivotally connected to the platform of said truck and having tonguesat the upper edges of its side flanges engagin in slots in the base ofsaid housing and clinched thereover.

8. In a toy crane, the combination with a base, of a hoist arm mountedthereon, a drum carried by said base, an electro-magnet carried by saidarm, a flexible connection between said magnet and drum passing oversaid arm, and a handle at one end of said base provided with anelectrical contact.

9. In a toy crane, the combination with a hoist arm, of a pulleyrotatably mounted thereon, and a guide for the flexible member passingover said pulley, comprising a U-shaped member embracing the flexiblemember below said pulley.

10. In a toy crane, the combination with a base, of a housing mountedthereon, a hoist arm and an electro-magnet carried by said arm, of ahandle integral with said housing and reinforcing beads in said handleand base.

In testimony whereof I affix my signature.

GEORGE ZAHORSKY.
